Patent DE-3137933-A1 (DE)
Title: Arrangement for mass balancing in a reciprocating-piston crankshaft engine
Inventor: GONSKA WALTER DIPL ING
IPC: F16F15/26
Filed: 1981-09-24
Abstract: The invention relates to an arrangement for mass balancing in a reciprocating-piston crankshaft engine with at least one balance weight, which is driven in phase opposition to the working pistons by the crankshaft via a balancing connecting rod and is guided by means of a rocker held pivotably on the engine housing so as to perform an oscillating motion on an essentially linear path. In order to avoid an inherent increase in the overall width of the crankshaft engine, the rocker is, according to the invention, to be arranged essentially parallel to the axis of the crankshaft. In order to make this possible, the articulation of the rocker on the balancing connecting rod and the articulation of the connecting rod on the crankshaft or that of the rocker on the fixed housing must be designed in such a way that pivoting movements about two mutually perpendicular axes are possible. <IMAGE>

Title: Round-bale press
Inventor: KRONE BERNARD
IPC: A01F15/07
Filed: 1981-11-23
Abstract: The machine for picking up and pressing agricultural crops, such as hay and straw, to form roll-shaped bales consists of a winding chamber which is movable by means of an undercarriage and which possesses, for opening the winding space bounded by it, a rearward part which can swing up about an upper horizontal axis. The winding chamber comprises two plane side walls forming the end faces of the winding space, a circumferential limitation formed or run over by conveying means and surrounding the winding space at the front, at the top and at the rear and, in its lower region, a horizontal draw-in gap, in front of which a pick-up device for the crop is arranged. To make the machine cheaper and simpler and to reduce its drive power, the circumferential limitation of the winding chamber also itself directly surrounds the winding space on the underside and is brought directly up to the draw-in gap and the pick-up device.

Title: Arrangement for controlling the tensile force of an extruded bar emerging from an extrusion press and passed through a calibrating device
Inventor: HEIN THEO
IPC: B21C31/00
Filed: 1983-03-02
Abstract: In an extrusion apparatus, the permissible tensile force for the extruded strand is controlled constantly by means of an adjusting cylinder for the calibrating device. When accelerating the extruded strand from standstill to the rated speed, the adjusting cylinder is controlled as a function of displacement until the calibrating device carried along by the extruded strand comes to rest gently on the piston of the adjusting cylinder. The system is then switched over to control as a function of the tensile force. On the control device for the adjusting cylinder, there is superimposed a rotational-speed control device of the drive motor for the transport device of the extruded strand, which device guides the piston of the adjusting cylinder back into the central position. <IMAGE>

Patent DE-3312317-A1 (DE)
Inventor: POLLMEIER KONRAD
IPC: D05B39/00
Filed: 1983-04-06
Abstract: An apparatus for holding tubular goods for stitching at the station of a sewing machine has a support adjacent the sewing station, a drive for rotating the support about a horizontal support axis, and at least three arcuate segment plates displaceable radially of the support axis on the support and together forming a segmented drum centered on the axis. The plates are displaceable between inner positions defining a circumference smaller than that of the smallest tubular goods to be sewn and outer positions defining a circumference larger than that of the largest tubular goods to be sewn. The plates can be radially spread on the support to change the diameter of the drum. Thus when a tubular workpiece is fitted over the drum it is tensioned thereover. The support can also be displaced vertically adjacent the station to align the uppermost segment plate generally with the stitch plate. The support is a disk formed with respective radial guides and the plates have radially extending elements received in the respective guides. The radial elements have radially outer ends pivoted on the respective plates and radially inner ends.

Title: Collet chuck
Inventor: IHLOW ROLF
IPC: B25B13/52
Filed: 1983-10-13
Abstract: A collet chuck which has two legs, designed as a grip, that can be pressed together and are pivotable about a common bearing axis, the clamping parts of the chuck being stressed by the movement of the legs, is to be so designed as to make it possible to produce and dismantle pipe connections even at relatively inaccessible places without the need for costly mortising work. To this end, provision is made according to the invention for the first leg to be connected to a tensioning strip which is curved in the form of an arc of a circle and whose other end is mounted, in an articulated manner, on the second leg on this side of the bearing axis, the tensioning strip being contracted when the legs of the chuck are pressed towards each other.

Title: Thermal insulating board with a covering and a particulate, highly disperse thermal insulating material compressed in the covering, as well as process for the production thereof and device for carrying out the process
Inventor: KUMMERMEHR HANS
IPC: E04B1/80
Filed: 1983-12-30
Abstract: A thermal insulating board of microporous insulating material (2) based on microporous silicic acid aerogel is provided with a covering (1) in the form of a composite film (1a), in which the pulverulent insulating material (2) is pressed to board form. The composite film consists predominantly of a cheap material such as paper as inner layer (21), which, however, has a lower flashpoint than the normal service temperature of more than 500 DEG C and therefore would burn upon heating with strong evolution of dense smoke and odour. The outer layer (22) of the composite film (1a) is formed by an aluminium foil some  mu m thick, which provides an air seal in the paper lying behind it, so that this does not burn but only cracks. For the escape of air necessary during pressing, in particular the region of the seams (4, 5) is used, which seams are kept air-permeable with long stitch seams. To aid this, perforations (24) can also be introduced into the composite foil (1a), which because of the small hole diameter do not permit escape of thermal insulating material (2) during pressing. If the hole diameter of the perforations (24) is suitably small no clenching effect of any kind between the insulating material (2) and the covering (1) occurs, so that the thermal insulating board is readily flexible. <IMAGE>

Title: Apparatus for sealing tube-like package wrappings
Inventor: NIEDECKER HERBERT DIPL ING
IPC: B65B51/04
Filed: 1984-04-04
Abstract: There is a need, especially in the case of vertical apparatuses for sealing tube-like packages with U-shaped sealing clips 6 which are individually fed to the clip guiding channel 3, to create the possibility of using not just sealing clips 6 with a cross-sectional breadth for which the inside width of the clip guiding channel 3 has been designed, but also sealing clips 8 with a smaller cross-sectional breadth. This object is achieved by using a stamp 2 in such sealing machines, in which stamp the longitudinal side of the stamp shank 4 facing the clip inlet 7 is reduced in thickness towards the end 5 in a tapering fashion until the thickness of the end 5 of the stamp 2 amounts to no more than 85% of the thickness of the stamp shank 4. <IMAGE>

Patent DE-3418118-A1 (DE)
Title: Boosting energy from flowing water
Inventor: HERBRAND LUDWIG DIPL ING
IPC: F03B17/06
Filed: 1984-05-16
Abstract: Large quantities of energy that are not developed are stored in clouds or in artificial lakes like coal in a mine. In order for these to be used, the potential energy which depends on the weight of the stored water and on the dynamic head, has to be converted into kinetic energy, which depends on the mass of the stored water and on the square of the velocity with which the mass is moved. It is found in flowing water, in streams, rivers, ocean currents or the like. A linear increase in the velocity before the energy is used causes a quadratic increase in the energy. Consequently, machines that are driven by water can provide more power than there is power contained by the unused forces. It is of no consequence whether the increase in velocity, which already takes place, for example, by a reduction in cross-section, is undertaken in the feed or in the turbine.
